    Wiring question for Paragon

    You can use a DPDT on/off/on toggle switch instead of the dip switches. The switches in the KoT allow for 4 possible combinations, but the manual only describes and intends use of 3 of them - soft clipping (one switch up), hard clipping (other switch up), or no clipping (both switches down)...

    Anybody Use A Small T-Square?

    I'd like to get a smaller one that slides better and is maybe a bit nicer and without a center detent, but buying tools is a slippery slope. A super sharp pencil is my other favorite tool. These oversize ones are my favorite

    Anybody Use A Small T-Square?

    I use a 12" Empire combination square for my drilling layouts. You can use it to make sure each pot hole is in alignment, and you can set it as a depth gauge and make sure they are centered and/or spaced evenly as well. It would be nice if it had 32nd increments, but the 16ths are okay for what...

    Bring out yer Diptrace

    I spent some time with the data sheets updating the pad and hole dimensions for the jacks, as well as some cut outs in the board for the enclosure screw bosses. I think it's ready! (in this pic the in/out audio jacks are reversed)

    Bring out yer Diptrace

    Here is a Resinite OD (Amber Overdrive), probably my favorite distortion circuits. While making this I learned it's a big muff, and I don't know how I feel about that. I wanted to make it without any off board components. It uses these jacks which are smaller than the Neutrik style. I was...

    Pitfalls and Tips: Designing effects PCBs

    I'm watching a ton of vids on board layout, mainly on how to reduce or eliminate noise. I'm noticing that they all seem to be based on boards that operate with freqs in the mhz and ghz range, and/or have switching power supplies. Our boards are in the much lower audio range and have a low...

    Designing PCBs with board mounted jacks

    I'm doing this now as well. I'm thinking the flat plastic part of the jack that the threaded part sticks out from should be flush against the inner wall of the enclosure. The jack should be nutted (smh) onto the enclosure semi tightly so it is secured but still able to be rotated, and then the...

    LED brightness

    LEDs come in a range of brightness. If your LED is too bright then increase the 4k7 resistor to something like 6k8. It's helpful to set up a small breadboard with an LED so you can try different resistors and get an idea for what you want to install to the PCB

    Poison apple. help me think through what I am seeing

    Try different op amps for that light distortion. The TL072's you have look sus The middle pin of the L78L05 is supposed to be ground. If you are getting continuity between pin 1 and 2, then your 5v supply is shorting to ground somewhere. Check anywhere that 5v is present, like Q2, Q3, and the...

    Wiring Question: Two Circuits on One Stomp

    The grounds are fine as it is. Each ground is connected to each other so it doesn't matter where they go as long as they are all linked

    when to use mlcc capacitors

    I harvested my tants from a failed project so I've done my good deed for the year

    Bring out yer Diptrace

    I drew this up - it's the same circuit as before (Mastema Drive) but laid out on a 1590bb with everything mounted to the board. If this were a pedal I would make, I would use the audio jacks that have a collar nut that secures from the outside. The power jack would be recessed, and the LED trim...

    when to use mlcc capacitors

    I love seeing old Fender and Gibson guitars that have a big ceramic capacitor for the tone control. I think of this kind of discussion every time. https://www.rickn-guitars.com/electricals/gib_electricals.html NOS High Voltage Ceramic... "excellent sounding" It may be that the limitations...

    when to use mlcc capacitors

    I use MLCC when the only alternative is a ceramic cap, or if there isn't space on the board for a film, or if for some reason the build doc calls for it. For instance, I'm building an Aion Xenotron, which needs 100nF MLCC's for the power supply and BBD filtering sections. Typical values for an...

    Kliche Overdrive - No Input?

    It's okay. It's worth taking the time to do it slowly and cleanly because it'll save you more time later on This is a Skylight Overdrive, it's a Mad Professor Sky Blue circuit. Just remember with soldering, go slow and try to enjoy it. You will develop speed thru repetition.

    Kliche Overdrive - No Input?

    The most common culprit is poor soldering. In your power jack alone you can see stray strands of wire. That kind of thing needs to be cut short. When you solder, start by stripping off 1/4" of insulation from the wire, twisting the strands together, then tinning the wire. Tinning is when you...

    Bring out yer Diptrace

    I've noticed what seems like your earlier layouts are 1590b sized and the component fit is very tight, like on the Seabed Delay. I like these boards as they look great and are very satisfying to build. The (presumably) later boards have components spaced further away from each other. Is there an...
